.To @ZZ whom it may concern.-

Be it known that I, ROBERT A. CARTER, re-y siding at Pittsburg, in the county o'f Allegheny and State of Pennsylvania, a citizen of the United States, have-invented or discovered certain new and useful Improvements in Piles for the Manufacture of Iron Sheets, 8m., of

, which improvements the following is a speciits object such a construction and arrangement of the parts forming the pile as Will permit of a more thorough permeation ofthe heat throughout the pile and the escape of the cin`l der therefrom during the heating operation; and to these ends the invention consists in the construction and combination ofv parts, substantially as hereinafter described andclaimed..

It has heretofore been customary in forming piles to first squeeze the puddled balls to remove the slag and cinder and toixnpart a suitable shape thereto for subsequent rolling; next, to reduce such shapes into bars in muck-rolls; then to cut the muck-bars into suitable lengths; and,iinall y, to arrange the out sections into'suit- -able piles, which are then charged into a hea-ting-furnace. In the practice of my invention, however, the puddled ball is takendirectly to a suitable hammer and there hammered outinto a plate of any'desi red size proportional to the size of the pileto be formed. After the plate l has been hammered out, as described, a series of grooves, 2 and 8, are formed in one side of the plate, (by placing an iron bar of suitable dimensions across the plate and then forcing the bar into the same any desired depth by blows 'of the hammer.) The number, size, shape, or

tions throughout the pile in which suehplates are incorporated and the escape of slag and cinder therefrom.

In forming'piles with plates prepared as above described, one plate is arranged with its grooved surface uppermost, and onthisis lplaceda similar plate with its grooved surface down; or, if these two plateswill not form a pile of the desired size, one or more plates, 4, similarly grooved on both sides, as shown in Fig. 4, can be interposed between the upper andglower outside plates, which are technically known as covers, or any other suitable iilling-a g., muck-bar sections.

Asy will be observed, the above-described construction and arrangement of the plates and covers will permit of the ready accessv ofthe l heatv to the inner as well as to the outerl portions -of the pile, thereby insuring not'only a .more rapidheating of the entire pile, but also a more even distribution of the heat throughout the entire mass.

'In lieu of forming the grooved plates under a hammer, as described, the puddled ball may be passed through the squeezers, as is usual,

and then rolled to plates of the desired dimen-` sions, vand nally grooved .by passing. the plates through suitably-constructed rolls; but'I prefer toform such plates under ahammer, as being more expeditious and cheaper.

As the principal characteristic of the invention herein is such a construction of piles as to permit of the ready permeation Vof heat into and through the interior of the pile and the escape of cinder or slag therefrom, it is evident that the same purposes may be effected by forming a series of ribs or projections on the face of the plates or covers, as clearlyl shown in Fig. 5. The projections or'ribs maybe formed either by for-ming plates of suitable width or thickness into the plates or covers while hot, by blows of the hammer, orby passing said plates between suitably-grooved rolls, as will be readily understood by those skilled in the art.

I am aware that piles for railroad-rails have been -made having a longitudinally-grooved base-slab and muck-iron head-slab, the grooves in said slabs being for the purpose of engaging the iianges of rail-sectionsY forming the body of the pile; butin such construction no provision is made for the penetration of heat in all directions into the body of the pile, asis attained by the construction claimed by me. 5 I claim herein as my inventionv 1. A pile consisting of two or more plates or covers havingportions of their surfaces de pressed, thereby forming grooves and projections, and arranged with their depressed surxo faces adjacent to each other, for the purpose of forming passages through and into the piles, substantially as set forth.

2. A pile having, in combination, plates or covers provided with projections and a suit- :5 able filling, the plates and filling being arranged n such relation to each other as to form passages through and into the piles, substantially as set forth.

3. A pile having a grooved cover, the

'grooved surface thereof being arranged adja- 2o cent to the body of' the pile and in such relation thereto asgto form passages through and into the body of the pile, substantially as set forth.
